This has to be one of the most humbling and upsetting experiences, but essential if you can get there.
The Menin Gate Memorial to the Missing is a war memorial in Ypres, Belgium, dedicated to the British and Commonwealth soldiers who were killed in the Ypres Salient of World War I and whose graves are unknown.
Following the Menin Gate Memorial opening in 1927, the citizens of Ypres wanted to express their gratitude towards those who had given their lives for Belgium's freedom. Hence every evening at 20:00, buglers from the Last Post Association close the road which passes under the memorial and sound the "Last Post". Except for the occupation by the Germans in World War II when the daily ceremony was conducted at Brookwood Military Cemetery, in Surrey, England, this ceremony has been carried on uninterrupted since 2 July 1928. On the evening that Polish forces liberated Ypres in the Second World War, the ceremony was resumed at the Menin Gate despite the fact that heavy fighting was still taking place in other parts of the town.
